' WIRELSTRINGING PILOT.

Application med september 2o, 1927. semina. 220,820.

The present invention relates to wire stringing pilots, and aims to provide a novel, and improved deviceto facilitate the stringing of telephone, telegraph, and other electric wires over the cross-arms of the poles which carry-the wires. Y

'Another object of lthe invention is the i provision of a pilot .of novel form Vto which the wires are attached and which is adapted to be pulled over the cross-arms so `aste properly position the wires thereon.

With the foregoing andk other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit f the invention.

The invention is Yillustrated inthe accon1- panying drawing, wherein- Figure 1 is a plan view ofthe pilot.

Fig. 2 is a cross section thereof on the line 2-2 of Fig. 1.

Figs. 3, 4, 5 and 6 are perspective views illustrating the successive steps in Stringing two wires over a cross-arm by means of the pilot.

The pilot is pressed from sheet metal, and has a pointed forward end, with its edges diverging rearwardly. The pilot has a depressed longitudinal runner 10, the forward portion of which is curved upwardly to the tip 11, and said runner has the inclined sides 12`and 13, the side 12 being of greater height than the side 13 and extending to the corresponding edge of the pilot. From the side 13 of the runner there extends a broad wing 14 which is disposed substantially parallel with the plane of the edges of the pilot and below same in a horizontal plane with the pilot disposed horizontally as seen in Figs. 1 and 2. The corresponding edge portion 15 of the pilot extends upwardly from the wing 14, and said edge portions of the pilot converge forwardly to the tip. As shown, the edges of the sheet metal are bent back inwardly, as at 16, to stiffen and reinforce the marginal portion of the pilot. The wing 14 is formed at its .rear end with a recess or cut-away portion 17 for the purpose which will hereinafter appear.

The pilot is provided at its rear corners with apertures 18 to which the wires 19 may be secured, so as to be drawn forwardly with the pilot.

A rope 20 or other flexible element is connected to the forward end or tip of the pilot. -As shown, an eye 21 is swivelled to the tip 11 and the rope 2O is connected to said eye, thereby permitting the rope to rotate without the pilot. The rope 20, as seen in Fig. 4, may also be provided with a swivelA joint 422m advancevof the pilot, and either or both of the swivel joints may be used. v

A tail rope or liexible element 23 is provided to prevent the pilot from rotating, which ifiit occurred would cause the wires 19 to be twisted together. The rope 23 is fastened by a clamp 24 to the portion 12 of the pilot at the rear end thereof, and passes downwardly out of the rear end of the runner 10. f

In using the pilot, with the wires 19 secured in the apertures 18, the rope 20 is thrown over the cross-arm 25 of the pole, and its freeV end is then pulled so as to pull the pilot up toward the cross-arm, as seen in Fig. 3, and the rope 23 may be held so as to prevent the pilot from rotating. By pulling the rope 20 the wires 19 are pulledv taut, as seen in Fig. 4, and the( pilot is then pulled overthe cross-arm, as seen in Fig. 5, the runner 10 riding onto and over the cross-arm and moving between the pins 26 or the insulators (not shown) if the insulators are already secured on said pins. The runner 10 will pass between the pins, and the wing 14 will ride over one of the pins, as seen in Fig. 5, thereby positioning the wires over the cross-arm at opposite sides of said pin,

The wing will bear down on the pin'or insulator over which it moves, and the recess 17 will enable said wing to` move oli' said pin or insulator before the rear end of the runner moves-off the cross-arm 25. Fig. 6 shows the pilot leaving the cross arm with the wires being pulled over said cross-arm, f

and the tail rope 23 will also be drawn over the cross-arm.

When the wires have been pulled forwardly suliciently, the rope 2O is thrown over the cross-arm of the next pole and the operation is repeated.

BythrowingV the rope 20 over the crossarm between the pins 26 towhich the wires are to be connected, the pilot will be pulled over the crossarmin such a manner as to properly position the wires over the crossarm without the liability ot the wires becoming tangled or twisted, and the pilot will ride over the cross-'arm without interference.

Having thus described the invention, what is claimed as new is: v

l. A wire Stringing pilot liavinga runner to ride over the cross-arm of a pole, provision at the forward end of the runner for the attachment of a flexible pulling element, and provisions at opposite sides of the rear end of the runner for the connection of wires to be pulled. y

2. Afsheet metal wire stringingpilot hav- Aing its edges converging forwardly into a tip, a depressed runner extending rearwardly from saidtip, provision at said tip for the attachment of a ilexihlepulling element7 and provisions at the rear ends of said edges for the connection of `wires to be pulled.

3. A sheet rnetal wire Stringing pilot having its edges converging forwardly to a tip, a depressed longitudinal runner extending rearwardly from said tip, provision at sai tip forithe connection `of a flexible pulling elementya broadwing` at one side of said runner, and provisions at the rear ends of said edges for the connection of wire to be pulled.

4. A sheet metal Wire stringin pilot havingits edges converging forwar ly to a tip, provision at said tip Afor the connection of e, flexible pulling element, a depressed runner extending rearwardly from said tip, provisions at tlierear ends of said edges for the connection of wires to be pulledyand a flexible tail element secured to' said ilot and extending from the rear end` of sai runner.

In testimony whereof `I` hereunto ailix my signature.
